2. Faulty Antenna
If your Mercedes radio is experiencing reception issues or no signal at all, the problem might lie with the antenna. Consider the following:

4. Software or Firmware Issues
Software or firmware glitches can also cause the Mercedes radio to malfunction. Try the following:

- If you recently updated the vehicle software, ensure it has not affected the radio’s functionality.
- Perform a hard reset by disconnecting the vehicle’s battery for a few minutes to reset the system.
5. Internal Hardware Failure
If none of the above solutions resolve the issue, it is possible that your Mercedes radio may have experienced internal hardware failure. In such cases, professional diagnosis and repair may be necessary. Contact an authorized Mercedes service center for assistance.
In conclusion, when your Mercedes radio is not working, it can be due to various factors ranging from power connection issues to hardware failures.
